    Abstract

    Simple calculation methods in 1D and 2D have been developed in order to determine the temperature development of the steel casings and columns when external gas temperatures are known. The methods have been validated on the basis of a standard fire test and natural fire tests carried out using the VTT façade test rig. Very good agreement between calculations and test results was found using the 1D-method and also the 2D-method under symmetric fire exposure. The agreement is not quite as good for the 2D-method under asymmetric fire exposure. Higher asymmetry leads to less accurate results due to the high nonlinearities in temperature distributions. However, the results are mostly conservative for these cases as well. A 1D-temperature calculation method for layered steel balcony structures has also been developed by VTT. However, due to lack of space, only a short presentation of this method can be included in this paper.
